About AROTEC Diagnostics

Who we are
Founded by Neil and Doris Cook, AROTEC has been producing and delivering the highest quality, critical components to the autoimmune diagnostic industry since our incorporation in 1996. Based in Wellington, New Zealand, AROTEC Diagnostics has grown over the years to become a valued and trusted supplier of premium reagents to both IVD companies, research and academic groups.

Since AROTEC's inception we have undertaken a concerted effort to produce both established and novel autoantigen reagents under stringent quality management procedures with a key emphasis on process control and continual improvement.  From our beginnings we have placed our main focus on autoimmunity and as we evolve we are actively expanding this portfolio adding new native or recombinant antigens and antibodies to provide a comprehensive product range for many autoimmune disease states.  As part of our future plans, we will be investing in research and development to deliver the same quality products you have come to expect from AROTEC while also looking at other disease states.
What we do
AROTEC is a practical, hands-on scientific company with over 75% of our staff coming from a biochemistry or biotechnology background. We are purification experts with years of experience, which has allowed us to master complex purification processes and produce premium diagnostic reagents from analytical to bulk scale. Carrying out continuous in-process analysis using an array of analytical proteomic techniques, we can maintain tight process control resulting in less lot-to-lot variability and a final product that conforms  to our product specifications batch after batch.

We believe that there is no compromising when it comes to quality. To purify quality reagents it is necessary to start with quality raw materials; autoantigens purified from animal tissue are from animals of exclusively New Zealand origin, the premium source material. Human blood fractions are obtained from certified blood centres with complete donor traceability and serology. Our commitment to quality is no more evident than in our range of purified autoantigen reagents, which display the following outstanding characteristics:

Purity – our autoantigens are highly pure (minimum specification >90% pure but often approaching >99% pure). We achieve this through meticulous “polishing” of the final product using high-resolution chromatographic techniques. This results in the virtual absence of contaminating substances thereby ensuring that assays developed using our autoantigens have very low background.

Activity – our autoantigens are highly active and can be used to detect autoantibodies in ELISA even when coated at low concentrations (typically 10-100 ng/well is sufficient).

Specificity - active immunoadsorption procedures where necessary followed by rigorous quality control ensures that our autoantigens are free of other autoantigens that might lead to false positive results.

Reproducibility – lot-to-lot consistency is our strength. New lots are rigorously tested and compared to internal gold-standard lots to ensure they conform to specifications.

Volume – we can produce autoantigen lots from analytical (a few milligrams) to bulk (approaching grams) amounts. Large lots eliminate the need for customers to continuously qualify new lots during production. Autoantigen lots can be reserved for established customers.

Stability – our autoantigens exhibit outstanding stability characteristics and show no significant loss of activity over several years when stored appropriately.

Availability – except under exceptional circumstances we maintain high inventory levels of our complete product range thereby ensuring punctual delivery.

Value – excellent quality doesn’t mean that a product is unaffordable! We will make every effort to supply to you at competitive prices. 


Securing the order is not the end of the story for us. We will advise you on the best way to get your product safely delivered and how best to store and maintain it. We will communicate with you to make sure sufficient bulk product is available when required and for pilot samples to be despatched. We will gladly talk to you about a product lot reservation strategy that suits your production process. We are delighted to supply product performance and application data to customers.

Should any queries result from the use of our products we go to great lengths to follow up and help resolve the situation to the complete satisfaction of the customer.



Looking for a novel reagent (antigen or antibody)? Need one of our products with a different specification? Have something that needs to be purified?

At AROTEC we will work with you to solve your purification needs. Our range of protein/antibody purification and conjugation techniques, and our experience with recombinant proteins may be just what you’re looking for. Talk to us about your project, whether you are looking for a custom service provider, or if you just want our feedback on what you are looking to do. We will take every effort to ensure the confidentiality and integrity of your business information.

What's new at AROTEC?
In late 2014, AROTEC Diagnostics was acquired by Water Street Healthcare Partners with a focus to significantly expand our portfolio to match the requirements of our research and diagnostic customers. As part of this increased investment, AROTEC moved to a brand new purpose built Facility within the Wellington region. This new 15,000+ Sq.Ft will enable us to address our future growth plans, allowing a larger R&D focus for new product developments and an overall increase in manufacturing capacity and productivity.

We have also hired technical sales managers in both Europe and the US to work more closely with you and ensure our plans are in line with market expectations and needs, as well as moving away from a distributor model and supplying direct to market.
